The plan of analysis used in the study. The patients were randomized into three primary groups based on the neuromuscular blocking agent received, as vecuronium, atracurium, and rocuronium groups and were compared. Each primary group was subdivided based on presence or absence of RNMB, and the subgroups were compared within and across the primary groups. Further, identical subgroups from all three primary groups were pooled and regrouped as RNMB-present and RNMB-absent groups and were compared. RNMB = residual neuromuscular blockade.
